SPECIFICATION forming part of Letters Patent No. 446,516, dated February 17, 1891.

Application filed September 3, 1888- Serial Ne. 284,503. (No model.)

To (tZZ whom, it may concern:

Be it known that I, EPHRAIM A. IIALDEMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door-Hangers; and I do hereby declare the following to be a full, clear, and exact description of the invention, that will enable others skilled in the art to which it pertains to make and use the same, referonce being had to the accompanying draw iugs, forming a part hereof, in which- Figure 1 is an elevation showing in full lines the door closed and in dotted lines the door open; Fig. 2, an edge elevation, partly in section, showing the door closed; Fig. 3, an edge elevation, partly in section, showing the door swung out and in position for opening; Fig. 4, a detail, partly in sect-ion, showing the sliding rack-bar and the movable support; Fig. 5, a sectional elevation edgewise through the sliding rack-bar and the movable support, showing the pinion for operating the rack-bar;

.Fi g. 6, a cross section through the door-frame,

showing the rack-bar, its o 'ierating-piuion, and the movable support.

This invention relates to door-hangers designed for use with sliding doors or doors which slide edgewise, such as freightcar doors and other sliding doors.

The objects of the invention are to dispense with guide-rails, shoes or rollers, carriages, and other appliances heretofore employed with sliding doors, and thereby simplify the construction and improve the operation of pivoted suspending-arms arranged in pairs for suspending and moving the doors; to construct a door-hanger of pivoted arms in pairs and pivoted links, which requires but the minimum of labor and force to open and close the door, and which at the same time gives the movement of the arms always in a straight plane for sliding the door in either direction, and thereby insure an easv movement in open in g and closing the door 5 to suspend the door from a movable support which can be raised and lowered to cause the door to enter and be withdrawn from its opening, and operating to have the door when closed flush or even with the outside wall of a car or other receptacle, or with the side or wall of a building or room with which the door is used, it

being understood that the hanger is applicable to doors lying outside of the plane of the wall with which the door is used, the feature of insetting the door being especially adapted forfreight-cars or other car-doors, by which the minimum of friction of air on the side of the car will be attained, the feature of insetting the doorintoits openingeffecting also increased safety and security, as the operation of closing the door will securely lock the same, and to improve generally the construction and operation of door-hangers, as hereinafter more specifically described, and pointed out in the claims, by which the door will always be in operative condition and the sagging thereof will be overcome and the door will always be in condition to be opened and closed with readiness and ease; and its nature consists in providing suspending-arms in pairs, each pair swinging from a fixed pivot and pivotally connected to the object to be moved for producing a straight-line travel for the object without changing the pointsot' attachment of the suspending-arms; in providing suspendingarms in pairs, each pair having a pivot and a pivotally-connected radial link to limit the horizontal movement of the arms; in providin g suspending-arms in pairs, each pair radiating from its pivot, a radial link, and a series of links connecting the suspending-arms with the movable object; in providing suspending-arms in pairs, each pair swinging from its pivot, a pivotal radial link, and a parallelogram connecting the movable object and the suspending-arms; in providing a series of links pivoted one to the other and swinging from pivotal points and pivotally connected to suspendingarms; in providing a movable support carrying suspending-arms in pairs and pivoted connecting-links between the arms and the movable object or door; in providing a movable support carrying a door, a sliding bar, and links connecting the support with the door-frame and sliding bar; in pro viding a compensating parallelogram forming a connection between suspending-arms and a movable object or door and pivotally connected to the arms and object; in providing a compensating parallelogram formed of links pivoted one to the other and auxiliary links and supplemental links for insuring a oonn cctiou between suspending-arms in pairs and a movable object, and in the several parts and combinations of parts hereinafter described, and pointed out in the claims as new.

The invention is illustrated in the drawings as applied to and used in connection with a door of a freight-car, which when closed enters and fills the door-opening, and the construction and operation of the several parts entering into the invention will now be described, such parts consisting of pivoted suspending-arms in pairs, each pair swinging from a fixed pivot, and a series of pivoted links, auxiliarylinks, an d supplemental links forming the door-hanger as a whole, which door-hanger can be applied to sliding doors generally where it is desired to have the door, in; opening and closing, move in the same plane.

In the drawings, A represents the frame of the doorway; B, stop-pieces secured to the side piecesof the frame for limiting the in ward; movement of the door; 0, the door; D, a. guide rail or strip at the top of the door; E, a guide rail or strip at the bottom of the door; F, a strip secured to the inside of the door and to which, in the construction shown, is secured the strip E, and G the sliding-support to which the door-hanger is pivoted. This upport, as shown, is formed of two sides (1 and; g standing at right angles to each, other, with the side g straight and the side g at its upper end projected or thrown, out, as shown in Figs. 2 and 3. This support is pivoted, to the side of the door-frame by links j,one end of each link being attached to a pin or pivot j on the sidepieceof the frame and the other end of each link being attached to a pin or pivot j" on the part g of the sliding; support G, as shown in Figs. 2, 3, 4, and 5. These pivoting-linksj allow the support G to move vertically, and by such vertical movement the support G is carried in and out by the action of the pivoting-links},

H, isa sliding bar having at its lower end a rack h. and entered into a groove it, formed therefor in the face, of one side piece of the door-frame and held in its groove so as to be free-to slide up and down by strips 7r", securedtothe side piece-of the door-frame over the slidingbai' H,,as shownin Figs.2,3,4,and 5. The sliding bar" H is connected with the support G, bylin-ksk, one end of each link kbein g attached to apin or pivot k" onthe part g of the support and the other end of each link being attached; to a pin or pivot 70" on the sliding bar H, so.- that as the sliding bar H is raised and lowered vertically the support G will be likewise raised and lowered,and at the same time the support G will be moved in or out, and these movements will occur by reason of the action of the pivoting-links It, which links.

carry the support G upward with, the movement of the bar H and at the same time carry the, support inward, and with the descent of the bar H the links 70 carry the support G: down and at the same time out.

I is the door-hanger, consisting of the primary links or arms a and a, constituting a pair of suspending-arms and both pivoted at one end to a common pin or pivot on on the part 9 of the support G to have the arm or link a adjacent to the face of the door 0, and other primary links or arms Z) Z)", constituting a pair of suspending-arms, are pivoted by a common pin or pivot 19 on the part 9 of the support G, as shown in Figs. 1, 2, and 3, and these suspending-arms in pairs at a and b b" are arranged for the arms of each pair to act together, and the arms are each of the same length, and from the pivot b a shorter link or arm I) swings, which link I) constitutes a radial link for limiting and regulating the movement of the other members of the construction that is causing the door or movable object to move in a straight line.

The primary arms or links a a and b I)" radiate in pairs from their pivotalpointsand their outer or free ends are pivot-ally connected tooompensating links and to auxiliary links, and the compensating links consist of a series ofi linksc, 0', (Land e,.which form when connected a compensating parallelogram, to one corner of which is pivoted the outer end of the link or arm a by a pin or pivot f, which also pivotally connects the link 0 to the link d, as shown in Fig. 1, and the arm orlink a is pivotallyconnected to the diagonally-opposite corner of the compensating parallelo gram by a. pin or pivot f which pin or pivot also pivotally connects the link 0 to the link 6, as shown in Fig. 1, and the radial arm or link I) is connected with a corner of the compensating parallelogram by a pin or pivot f which pin. or pivot also connects the link c with the link 0, as shown in Fig. 1, and the link 0 is connected with the link (1 by a pin or pivot f projecting from the stationary plate f, screwed or otherwise firmly fastened to the face of the door 0, connecting the diagonally-opposite corner of the parallelogram to that to which the radial link or arm I? is connected to a. stationary point on the door.

An auxiliary link cl is pivoted to the pin or pivot f, and a corresponding auxiliary link e is pivoted to the pin or pivot f and these auxiliary links cl and e are connected by supplemental links 0 and d", pivoted to a common pivot projecting out from. the platef. The free end of the link 0- is connected to the link 8 by a pin or pivot f which pin or pivot also connects the free end of the link or farm h, and the free end of link d" is. con- IZO the other when the dooris closed and by dot ted lines when the door is open.

J is a pinion secured to a stem J for its cogs or leaves to mesh with the rack 72, as shown in Figs. 5 and 6. I This pinion is located in an opening formed therefor in the side piece of the door-frame, which opening i is located in line with the groove 71, and one end t" of the stem J is squared to receive a key or lever by which the pinion can be rotated to move the bar 11.

K is the side of a car, L the roof of a car, and M the floor of a car.

As shown, a lug Z, having a slot 1, is socured to the upper end of the support G on the part g to receive the guide'strip D when the door is closed, as shown in Fig. 2, and to each side piece of the door-frame above the floor M is secured a plate m, having an inclined slot m for the passage thereinto of a pin m on the end of the guide-strip E, as shown in Figs. 2 and 3, by means of which slot and pins the door when closed is held from swinging out at the bottom and these slots and pins 771 and m" serve to guide the door when entering the doorway. A series of lugs 01, Figs. 1, 2, and 3, are arranged on the outside of the car in the same plane as that on which the door opens, and each lug n has a slot at to receive the guide-strip E to hold the door from swinging outward, and on the side of the car, as shown in Figs. 1, 2, and 3, is a series of lugs 0, each having a slot 0' to receive the guide-strip D when the door is open and hold the door in place at the top in opening and closing, the same as the lugs a hold the door at. the bottom in opening and closing.

The operation is as follows: The door-hanger I, when the door is closed, stands in the position shown in Fig. 1 with the primary arms a a Z) 0 Z)" radiating from their respective fixed pivots CL" and Z) and with their free ends attached, respectively, to the movable pivots carried by the compensating parallelogram and the auxiliary arms or links. The door, as shown in Fig. 1, is closed and entered into the doorway, and to open the door a suitable key or lever is placed on the square end i of the stem J and the stem turned for the pinion J to act on the rack h and carry down the sliding bar II, and in and by the descent of the sliding bar H the links 7t at the end attached to the bar II are carried down, drawing down such links, and with them the door B, and with the descent of the door the links j are turned down, forcing the door B out ward. The links j, when the door is closed, stand vertical, as shown in Fig. 2, and. the links 7;, when the door is closed, stand horizontal, as shown in Fig. 2, and as the support G descends by the action of the sliding rackbar II the linksj turn on their pivots j and the links it turn on their pivots 7c, the links also turning on their respective pivots j and 7t", and these links, when the door 0 has descended and been forced outward to a position for opening, will stand with the linksj horizontal and the links is nearly vertical, as shown in Fig. The guide-lug Z descends with the support- G, and as the door is suspened from the support G the door will descend and the guide-strip D will be in the lug Z, and as the door descends the pins m will pass out of the slots m, and the guide-strip E will enter the slot n of the lug at below the door, holding the bottom of the door against outward swing, and when down the guidestrip D aligns with the slots 0 of the lugs 0. The door is now ready for opening. The door, when in position for opening, is suspended from the support G by the hanger I, so as to hang free and clear for a slight exertion to move it into its open position, as shown by the dotted lines in Fig. 1, and in opening the suspending arms or links the compensating parallelogram, the auxiliary links in pairs, the radial link, the supplemental links, and the pivot-plate are carried over into the position shown in Fig. 1 by the dotted lines, so that the armor link a is outside, the arm or link Z) is inside, and the arm or link I)" in the middle, with the link 0 occupying the position of the link d, cl that of c, c that of e, c that of c, as shown in Fig. 1, and the other links accordingly, the several links assuming the different positions without changing the plan of the movement of the door by reason of the compensating parallelogram and the auxiliary and supplemental links. The door is closed by sliding it back into position shown in Fig. 1 with the door down, as shown in Fig. 3, and in this position the key or lever is turned to rotate the pinion J and raise the rack-bar II, carrying up with it the support G through the connecting-links 7., raising the door 0, and on the upward movement of the support G the linksj and 7.; turn and carry the door into its opening, the pins mpassing up in the slot m, and when the door is in place and closed and thekey or lever withdrawn from the stem J the door is firmly looked against opening until the stem J is again turned to swing the door down and out, as when the door is in place and shut the sliding bar H is locked and immovable, locking the support by the linksj and 7c.

The door-hanger I can be applied and used with an outside door or a door which does not close into an opening, and when so used the sliding support G is dispensed with, and the arms or links a ct Z) Z) Z) can be pivoted directly to the side of the door-frame, or to the side of the wall, or to a support aflixed to the door-frame or the side of the wall, as may be desired, and when the door-hanger is attached to a stationary support the guide-lugs n and o are to be arranged in the plane of the movement of the door to receive the guide-strips D and E to hold the door against outward strain at the top and bottom.

The door-hanger I is formed of two systems, an upper and a lower one, the upper system consisting of arms or links swinging from fixed pivotal points, and the lower sys tem consisting of arms or links attached to the door to be moved, and these two systems, arranged as described, operate together to carry the door in the same horizontal plane from its closed to its opened position, and vice versa, and this without any change in the relative positions of the points of attachment to the door and to the fixed object or pivotal point, except that as the door moves the fixed point of attachment thereon changes sides in relation to the fixed pivot from which the door is suspended, and the door will be held or sustained both vertically and horizontally and will be maintained in a direct line of travel from one side to the other without deviation in its course and without any sidewise turning, as in the movement the several levers and arms composing the doorhanger move simultaneously and parallel with each other by reason of their pivotal connection one to the other and their coacting relation.
